從冷氣起效
The Gradle project with Eclipse. Chinese output of Java Run can be displayed after setting "Properties" > "Resource" > "Text file encoding" to UTF-8.
Here is the Java code.
package testgradle;
import org.apache.commons.text.StringEscapeUtils;
public class Test {
public static void main(String[] args) {
String origin = "從冷氣起效";
String input = "\\u5f9e\\u51b7\\u6c23\\u8d77\\u6548";
String result = StringEscapeUtils.unescapeJava("\\u5f9e\\u51b7\\u6c23\\u8d77\\u6548");
System.out.println(origin);
System.out.println(input);
System.out.println(result);
}
}
I have tried to modify build.gradle file, but still the output of Gradle run is not as expected.
build.gradle
plugins {
id 'java'
id 'application'
id 'java-library'
}
jar {
manifest {
attributes 'Main-Class': 'testgradle.Test'
}
from {
configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }
}
}
application {
mainClassName = 'testgradle.Test'
}
tasks.withType(JavaCompile) {
options.encoding = 'UTF-8'
}
tasks.withType(Test) {
systemProperty "file.encoding", "UTF-8"
}
javadoc.options.encoding = 'UTF-8'
compileJava.options.encoding = 'UTF-8'
repositories {
jcenter()
}
dependencies {
api 'org.apache.commons:commons-math3:3.6.1'
implementation 'com.google.guava:guava:28.2-jre'
implementation 'org.apache.commons:commons-text:1.9'
testImplementation 'junit:junit:4.12'
}
Please provide solution to solve the problem. Thanks!
